<p><P>PROBLEM TO BE SOLVED: To provide a hinge device capable of stopping a movable member by every small angle, and preventing early abrasion and damage between recessed portions adjacent to each other in the circumferential direction. <P>SOLUTION: First and second spherical bodies 16A, 16B are disposed on a face opposite to a fixed member 12, of a movable member 14 in a state of being circumferentially separated from each other by 180°on a rotating axis. A face opposite to the movable member 12, of the fixed member 12 is provided with first recessed portions 19A, 19B and a second recessed portion 20. The first recessed portions 19A, 19B and the second recessed portion 20 are disposed so that the second spherical body 16B gets out from the second recessed portion 20, when the first spherical body 16A is put in one of the first recessed portions 19A, 19B, and the first spherical body 16A gets out from either of the first recessed portion 19A, 19B, when the second spherical body 16B is put in the second recessed portion 20. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
